Shohreh Razavy 7th August 2019 i Acknowledgements This thesis would not have come to a successful completion without the academic, scientific, and technical assistance, contribution and support from many individuals. My sincere appreciation goes to: My principal supervisor, Associate Professor Christopher Zaslawski, for the constant optimism and support throughout this long journey as well as his patience, motivation, and immense knowledge. Chris has given me all the freedom to pursue my research as well as allowing me to grow as a researcher, while positively and respectfully ensuring that I do not deviate from the core of my research. It should also be acknowledged that Chris was kind enough to undertake the editing work of each chapter of this thesis meticulously. The Associate Dean of Research, Professor Alaina Ammit, for her approval regarding the preparation of my thesis in the format of Thesis by Compilation. My co-supervisor, Dr Weihong Li, for being my secondary supervisor and providing the acupuncture treatment during the trial. The Tennis Elbow Acupuncture – International Study – China, Hong Kong, Australia and Italy (TEA-IS-CHAI) research teams, and in particular, Associate professor Shipping Zhang from School of Chinese Medicine at Hong Kong Baptist University for sponsoring my first manuscript to be published in the Journal of BMC. My colleague, Dr Bertrand Loyeung for providing his heartfelt support, invaluable guidance and inspiration at all times throughout my candidacy. I would also like to extend my thanks to Dr Sean Walsh for providing me invaluable advice on both future research opportunities, and my career.

All my friends from different disciplines; Traditional Chinese medicine, Mathematical and Physical Sciences, Environmental Science at UTS University who provided a much-needed form of escape from my studies, also deserve thanks for helping me keep things in perspective, in particular, Dr Nikta Shahcheraghi for her tremendous encouragements during my candidacy, and Paras Sidiqui for enlightening advice regarding my thesis structure. Finally, but by no means least, thanks go to my parents, my mother-in-law, my sister and my brothers for supporting and encouraging me throughout this experience. I am very much indebted to my beloved husband, Dr Mohammad Abdollah, who supported me in every possible way to see the successful completion of this work. iii Summary of thesis According to the theory of traditional Chinese acupuncture, acupuncture psychophysical responses (De-Qi) is a fundamental characteristic of acupuncture and believed to be indicative of a successful therapeutic acupuncture treatment. The phenomenon is understood to represent a constellation of subjective unique psychophysical responses of varying characteristics during the administration of acupuncture. Certain sensory responses are also thought to serve as an indicator for the dose of acupuncture needling. Qualities or characteristics of these sensory responses are often utilised to perform quantitative evaluation of acupuncture dosage. Hence, to ascertain the acupuncture-specific effects in an optimal way, it is essential to investigate this complex phenomenon into its constituent components. Furthermore, preliminary investigations indicate interoception to be reflective of De-Qi. Studies have reported that exposure of individuals to an unfamiliar situation or experimental study may cause anxiety, which is likely to influence sympathetic nervous system activity. It is also proposed that environmental or interoceptive signals are linked with a perceived sense of threat in anxious individuals which in turn may affect the perception of De-Qi in clinical settings. Recently several measures have been developed to quantify the potency and characteristics of the De Qi, as it is often reported that one of the major criticisms of acupuncture remains the lack of scientifically acceptable data and measurable efficacy. With this in mind, this dissertation examines the psychophysical responses experienced during acupuncture within the context of an acupuncture randomised clinical trial. At the same time, the thesis highlights the importance of understanding interoception and in particular the role of self-awareness, which may contribute to the placebo effect, and psychophysical responses that are often observed in clinical studies. Additionally, the role of pre-operative or situational anxiety in the elicitation of the acupuncture psychophysical responses was investigated. The study also investigates the influence of culture on individuals’ perception of acupuncture sensory responses and provocation of negatively valanced emotions such as situational anxiety. Finally, the thesis systematically and critically appraises all the existing scales developed to quantify acupuncture psychophysical responses by adhering to published guidelines such as the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and COnsensus- based Standards for the selection of health Measurement INstruments (COSMIN) quality criteria guidelines. iv Publications Razavy, S., Loyeung, B.Y.K., Walsh, S. & Zaslawski, C. 2019.
